Manganite compounds are known to host peculiar behavior such as colossal magnetoresistance, Jahn-Teller polarons and phase separation among other phenomena. In this experiment, we perform ultrafast electron diffraction experiments on freestanding La0.7Sr0.3MnO3 thin films. Ultrafast electron diffraction is a technique whereby an incident ultrafast pump pulse excites the sample into a non-equilibrium state and a probe pulse follows shortly thereafter, examining how the structure of the sample changes after excitation as a function of time delay. In this study, we observe that following the pump pulse, Bragg peaks show anomalous behavior in the form of enhanced coherence on a timescale of approximately 100 picoseconds. These results are discussed in terms of the melting of Jahn-Teller polarons.
